Description
INTRAORAL DEVICE, SYSTEM AND METHOD FOR INTRAORAL
MONITORING
CROSS-REFERENCE TO RELATED APPLICATION(S)
[0001] This application claims benefit of priority under 35 U.S.C. §119(e) of U.S. Provisional Patent Application Serial No. 63/115,956, filed November 19, 2020. The disclosure of the prior application is considered part of and is incorporated by reference in the disclosure of this application.
BACKGROUND OF THE INVENTION
FIELD OF THE INVENTION
[0002] The present invention relates generally to intraoral devices and more specifically to an intraoral sensing device, system and method for detection, monitoring and/or analysis of physiological data.
BACKGROUND INFORMATION
[0003] It is a standard safety precaution in many athletic activities for participants to wear mouth guards. Ranging from baseball, to gymnastics, to martial arts, mouth guards are designed to protect the wearer from impacts that would otherwise cause injury to the mouth. Mouth guards are shaped to take the brunt of the impact and shield the teeth, gums, and tongue from trauma.
[0004] With the advent of sensorized wearable devices, such as wristbands, athletes and doctors have begun to explore the potential benefit of using wearables for collecting physiologic data. Due to the pre-existence of mouth guards within athletic use, various attempts have been made to integrate different sensors with standard mouth guards. Most prominently, certain companies are developing and promoting mouth guards having sensors to measure acceleration and impact to an athlete’s head to assess whether a concussion may have occurred. In certain sports, e.g., boxing, wrestling, football and mixed martial arts, mouth guards are a required protective device. However, in other sports, e.g., baseball, track and field, soccer and basketball, among others, the use of a mouth guard may be discretionary. Hence, the inclusion of a protective mouth guard as a foundation to support data collection intraorally is not a requirement.
[0005] Data recorded from an athletic sensor, including a sensorized mouth guard, can be most useful if the data is available and actionable in real time. For example, a coach may rely upon data from a sensor to know if an athlete shows signs of being concussed, creating an opportunity for the athlete to be immediately removed from the game. Additionally, a coach might rely on data from one or more biometric sensors to know when to rotate out an athlete from play to reduce the risk of injury.
[0006] There exist many challenges associated with delivering data externally from a sensor deployed within an athlete’s body, including intraorally. For example, a wireless transmitter would likely need to rely on electrical power from a battery electronically coupled with the sensor. Typically, the level of power available would be very low. Hence, associated radio transmission signals would also be of the low-energy type. Consequently, attenuation of wireless signals transmitted from within an oral cavity would need to be addressed. Further, the wireless transmitter would need to be sufficiently robust to withstand the rigors of athletic activity. In certain instances, the wireless transmitter must be able to operate and withstand the same blunt-force impact against which a mouth guard is designed to protect, e.g., as in football.
[0007] Consequently, there remains a need for an intraoral sensing device, that is comfortable to the user, durable and that has wireless communication abilities to enable robust transmission of data to an exterior transmitter/receiver that is not placed on a user’s immediate body.
SUMMARY OF THE INVENTION
[0008] The present invention provides an intraoral sensing device, system and method for reliable and robust intraoral detection, monitoring and/or analysis of physiological data from a user of the device to allow for real-time decision making related to the user in a dynamic environment.

Thus, for example, references to “the device” include one or more devices, and references to “the method” include one or more methods, and/or steps of the type described herein which will become apparent to those persons skilled in the art upon reading this disclosure and so forth. [00021] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Although any methods and materials similar or equivalent to those described herein can be used in the practice or testing of the invention, the preferred methods and materials are now described.
[00022] With reference to Figure 1, the invention provides an intraoral sensing device 10 that includes a frame 20 (not shown in Figure 1) encased by a polymeric shell 30 which encases at least a portion of the frame, and a moldable component 40 composed of a polymeric material.

[00046] In some aspects, the method further includes assessing the hydration status or trend of an individual, and/or displaying (e.g., on a display device) an assessment of the hydration status or trend. Such an assessment can include, without limitation, an estimate of hydration status at a current time, a prediction at some point in the future, an estimate and/or prediction of a volume of fluid necessary for effective rehydration, an estimate of the
probability an individual requires fluids, an estimate that an individual has consumed or may consume an excessive amount of fluid which might result in hyperhydration, an assessment of the level of fatigue of the individual, and, a recommendation for changing the work load or activity of an individual.
[00047] In various aspects, the device of the invention includes one or more sensors that detect data associated with the physiological aspects of bodily fluids, both extracellular fluids and intracellular fluids. An understanding of dehydration affords an ability to ensure that appropriate physiological parameters are used to assess hydration. In addition to describing the present invention, the following discussion provides a framework for understanding the mechanics of dehydration and other related physiological parameters, as they relate to the invention of the disclosure.
[00048] Dehydration refers to a deficit of total body water (TBW) with an accompanying disruption of metabolic processes. Early symptoms of dehydration may include a strong feeling of thirst, weakness, nausea, and loss of appetite. Severe symptoms may include confusion, muscle twitching, and bleeding in or around the brain.
[00049] Dehydration carries the risk of osmotic cerebral edema if rehydration is overtly rapid. Cerebral edema is excess accumulation of fluid in the intracellular or extracellular spaces of the brain. In various embodiments, the device includes a hydration sensor configured to provide sufficient monitoring to avoid overtly rapid hydration. For example, during a high school football game in a hot and humid environment, a player may actually consume excess water. The sensor will enable tracking in a manner that allows a recommended amount of fluid/ electrolyte to be consumed based on each player’s individual physiology, including exertion, size, gender, age, and height.
[00050] For routine activities, an individual’s level of thirst may serve as an adequate guide to maintain proper hydration. With exercise, exposure to hot environments, or a decreased thirst response, additional water may be required above and beyond what a person’s level of thirst may indicate. Consequently, there is a need for an intraoral hydration sensor capable of tracking relevant physiological parameters to determine an individual’s hydration trend and status, and, to provide accurate guidance for fluid intake and replenishment in real-time.
[00051] Insensible water loss is defined as the amount of fluid lost on a daily basis from the lungs, skin, and respiratory tract, as well as water excreted in the feces. Insensible water loss is defined as loss that cannot be sensed. In contrast, sensible water loss is loss that can be sensed by an individual. Therefore, sensible water loss includes both urination and sweat. In assessing trends of hydration, algorithms associated with the hydration sensor or processing components for use with the invention consider aspects of both insensible and sensible water loss to provide a hydration assessment and suggest recommendations for therapeutic intervention, e.g., fluid replenishment, rest or activity reduction.
[00052] In various embodiments, the device includes one or more electronic components in communication with the one or more sensors, e.g., hydration sensor, which separately or collectively, include instructions for analysis of data applicable to an assessment of a person’s health status, such as hydration or cerebral status.
[00053] In another embodiment, the invention provides a system which includes the device of the invention in wireless communication with a remote computing device or cloud having functionality to receive, process, analyze and/or display data from the device. [00054] In various aspects, the device can communicate via a network. In aspects, the wireless communications module includes a Bluetooth® digital wireless protocol so that the device may communicate with a cloud and/or mobile computing device. Bluetooth® technology provides a low-cost communication link. The Bluetooth® transceiver may be configured to establish a wireless data link with a suitably equipped cloud, mobile computing device and/or another device of the invention. In some aspects, a device of the invention may operate in conjunction with another device of the invention.
[00055] As used herein, the term “mobile computing device” refers to any one or all of cellular telephones, tablet computers, phablet computers, personal data assistants (PDAs), palm-top computers, notebook computers, laptop computers, personal computers, wireless electronic mail receivers and cellular telephone receivers, multimedia Internet enabled cellular telephones, multimedia enabled smart phones (e.g., Android® and iPhone®), and similar electronic devices that include a programmable processor, memory, a communication transceiver, and a display.
[00056] The device of the invention may also include functionality to communicate via a long-range wireless network which is a component of the system of the invention. In one aspect, the long-range wireless network includes a cellular network. In another aspect, the long-range wireless network includes a multimedia communications network. In another aspect, the long-range wireless network includes wireless technologies such as Global System for Mobile Communications (GSM), Code Division Multiple Access-One (cdmaOne), Time Division Multiple Access (TDMA), PDC, Japan Digital Cellular (JDC), Universal Mobile Telecommunications System (UMTS), Code Division Multiple Access- 2000 (cdma2000), and Digital Enhanced Cordless Telephony (DECT).
[00057] The device of the present invention may also include functionality to wirelessly communicate with a remote server or network. As such, in one aspect, the system of the invention includes a remote network, such as a cloud computing platform.
[00058] There will be three forms of data transmission to that cloud storage, with an automated process that determines the optimum communication channel to use based on the environment the device is in:
[00059] In some aspects, the system includes a cloud-based data storage environment between the device and a mobile computing device. The cloud may include functionality to both store and present back data, and may also be interrogated by an artificial intelligence engine to derive a range of predictive analytics that will learn from the continuous data flow from all devices activated in the system.
[00060] In some aspects, WiFi data is transmitted from the device in real-time to the cloud data storage environment and the mobile computing device presents data gleaned from the cloud data storage. In some aspects, in the absence of WiFi, using a cellular connection, data is transmitted from the device in real-time to the cloud data storage environment and the mobile computing device presents data gleaned from the cloud data storage. In some aspects, in the absence of WiFi and cellular, using a Bluetooth® connection, data is transmitted from the device in real-time to the mobile computing device for immediate data presentation of current data. Once connectivity from the mobile computing device via WiFi or cellular is available, data is transferred to a cloud data storage environment. In some aspects, in the absence of WiFi, cellular and Bluetooth®, data is stored onboard the device
for extraction and uploaded via the mobile computing device, post-game once a WiFi or cellular connection is available.
